    how to increase the jpeg decode speed by opencv or other library?

    hss

      I use opencv(version 2.4.9) function imdecode to decode a 1600*1200 jpeg to grayscale bitmap in memory, the edison uses 400~500ms to do this(by one core).

       

      I tried another jpegdecode library (compiled by source code), it cost 4s.

       

      so , how can I increase the jpeg(jpeg data in memory) decode speed?

       

      I want the speed is below 100ms in my project.
